INDICATOR.

SPECIFICATION forming part of Letters Patent N o. 636,368, datedNovember 7, 1899. Application filed May 1, 1899. SerialA No. 715,154..(No model.)

To @ZZ whom it may concern:

Be it known that I, DANIEL H. VERNEUILLE, 'a citizen of the UnitedStates of America, and 'a resident of Mobile, county of Mobile, State ofAlabama, have invented certain new and useful Improvements inIndicators, of which the following is a specification.

This invention relates'to new and useful improvements inindicatingdevices, and especially to an apparatus designed for useparticularly upon steamboats and in the pilothouses,whereby the pilotmay know positively that when he has signaled to the engineer in theengineroom to actuate the reversing mechanism thev signal has beenproperly responded to by the showing of a card at a convenient locationto the pilot bearing the words Ahead or Back, accordingly as theleverreversing mechanism is operated.

More specifically the present invention consists in providing anindicating apparatus having display-cards adapted to belocated in thepilot-house, which cards are actuated by a reversing-bar which, as it isoperated by connections with the reversing mechanism in the engine-room,will cause one or the other of the cards to be disclosed and at the sametime ring a bell, which will serve as a means of acquainting the pilotof the adjustment of the reversing mechanism by the engineer in responseto the signal given by the pilot.

To these ends and to such others as the invention may pertain, the sameconsists, further, in the novel construction, combination, andadaptation of the parts, as will be hereinafter more fully described andthen specically defined in the appended claims.

My invention is clearly illustrated in the accompanying drawings, which,with the letters of reference marked thereon, form a partofthisapplication, and in which drawings similar letters of referenceindicate like parts throughout both views, in which- Figure l is anelevationshowing'the indicating apparatus set up in a pilot-house andhaving connections with the reversing mechanism in the engine-room. Fig.2 is a side view of the indicator enlarged.

Reference now being had to the details of the drawings by letter, Adesignates the indicator-containing box, which it is my purpose to havelocated in the pilot-house of a ship and convenient `to the pilot.Vithin this bo'X or casing are the two indicating-cards B and O, one ofwhich, as B, has printed thereon the word Ahead, while the second cardhas printed thereon the Word Back The card B is fastened to the upperend ofthe rod or bar D, while the lower end of said bar is fastened to alever E, which latter is pivoted fat E', adjacent to the gong F. Thespringactuated hammer G is pivoted at G and in such a position that itsfree end will be depressed by the free end of the lever E as the .end ofthe lever E, which is pivoted to the lower end of the bar D, is raised.As the free end of the lever E tilts down it strikes against the shankof the hammer, thus drawing down the hammer, which is spring-actuated,and Vallows the hammer to spring back and strike the gong and showingthe ahead card in the indicating-box, which is located in thepilot-house. This card B is so mounted in the casing that its edges willslide in slots B2 in the walls of the box. Mounted directly overthe"ahead card in said casing is the second card referred to, and thisback card C is guided in the same slots B2 and is connected to ak bar H,located directly behind the bar D, the upper end of which bar H may beforwardly bent, if desired, so that the two bars will not interfere witheach other. To the lower end of the bar H, which is slightly longer thanthe bar D, is connected the outer end of the lever K, which latter ispivoted at K to the casing, and its angled portion k is adapted tostrike against the pin k and actuate the hammer J as the outer end ofsaid lever K is depressed by lever H. As the angled portion lo passesthe pin 7c the free end of the hammer J will be drawn by means of thespring P against the gong L.

' For operating the levers and the indicators I provide the member M,which I term a reversing-bar, and which has an arm M' at right anglesthereto, which arm is designed to strike against Washers E2 and K2, thatare mounted on the pins E3 and K3, respectively at the ends of thelevers E and K, accordingly as it is desired to cause one indication oranother and to ring one or another of the gongs. Connected to the upperend of said member M is a coiledspring N, which in turn is fastened to arod O, carrying a nut N on its upper IOO threaded end. The office ofthis spring is to retain the member M normally at its highest limit, inwhich position the reversing mechanism of the engine is set to go aheadand in which position the ahead card will be indicated in thepilot-house.

In order to limit the movement of the two levers toward each other, Iprovide stops Q, and a coiled spring P is connected at its ends to saidlevers, the tension of which spring is supposed to return the levers totheir normal positions.

The lower end of the member M is connected to a wire R, which in turn isfastened to one corner of the angle-lever S. This angle-lever is alsoconnected at another of its corners to the wire T, and the opposite endof the wire T is connected to asecond anglelever W, to4 a corner ofwhich is also fastened one end of the rod V, the lower end of the latterbeing pivoted or otherwise connected to the cam-rod, as at V. Thereversing mechanism, to which no claim is made in this application, isof the ordinary construction and has connection with the cam-rod,whereby the cam-rod may be raised or lowered a short distance sufficientto actuate the indicating mechanism and to strike the gongs.

The operation of my invention is as follows: The indicator is set on theahead adjustment, in which position the reversing member M is at itshighest limit and the ahead card disclosed at the sight-aperture. W'henthe pilot signals to reverse the engine, as the reversing-lever in theengine-room is actuated the cam-rod is raised in the position shown indotted lines, and the member M is drawn down, the back card disclosed,and the ahead card drawn down out of sight.

the back card is disclosed the hammer J is 4o caused to strike the lowergong to give a signal to the pilot of the reversal of the lever.

From the foregoing it will be noted that the pilot will know positivelywhether the signal which he has given to the engineer has been promptlyand correctly complied with by the engineer. In the daytime the cardswill show and at night-time the two gongs, of different tone, will bestruck.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

1. Anindicating device forpilot-house,&c., comprising in combinationwith the eccentricrod and reversing mechanism of an engine, thespring-actuated indicator-bar having a right-angled extension thereon,the indicating-cards and bars connected thereto, the levers havingpivotal connections with the lower ends of said bars and washers ontheir pivotal pins, the gongs, and hammers actuated by said levers,which latter are adapted to trip the hammers as the spring-actuated baris operated, as set forth.

2. In an indicating device, the combination with the spring-actuatedindicatonactuating bar, the indicating-cards, the bars connected attheir upper ends to said cards, the pivotal levers and hammers adaptedto be actuated as the spring-actuated bar is operated, thereversing-lever and connections, as shown and described.
